Performance Evaluation of SWAT Model for Land Use and Land Cover Changes in Semi-Arid Climatic Conditions: A Review-- you can consult this article-may be of help

I can help you, please tell me what you need to investigate

Hi Naveed Ahmed. I normally analyze LU change scenarios as follows. First I calibrate and validate SWAT with the current LU scenario or whatever your baseline scenario is. Next I will re-run the model but modifying the LU input raster according with the scenarios of interest, and using the calibrated parameters that you came up with during the Calibration process. This approach implies that you create your scenarios of interest out of the model according with the problem that you want to analyze. One simple example would be analyzing a deforestation risk map you may identify future scenarios. SWAT also allows you to analyze BMP inside the model.

Thanks for your guidance @Sergio Miguel.

What is BMP?

Could you please explain to me.

Of course, BMP stands for "Best Management Practices". SWAT allows you to simulate the effect of things like: Terracing, Tile Drains, Contouring, Grassed Waterway, among others. You can investigate their effect on specific HRUs or subbasins. Additionally you can find them in the following tabs. Edit SWAT Input/Edit Subbasin inputs/SWAT Input Table/ Operations.

Thanks for your explanation.

Dear Naveed Ahmed ,

You might want to look into the references I provided in a project I am actively working on actually, as part of my PhD research. It is aimed at investigating the benefits of dynamic land use update in hydrological modelling. Link is here: https://www.researchgate.net/project/Hydrological-Modelling-Using-Dynamical-LULC-and-Future-Climate-Projections-in-a-Sahelian-Semiarid-Watershed

Take a closer look at Pai and Saraswat work on the topics, along with the SWAT-LUC tool. You might find it very interesting and suitable to your needs. The tool they developed (SWAT LUU) can be accessed online here: https://saraswat-swat.rcac.purdue.edu/

A recent evolution of the tool has been published recently, named SWAT-LUP, and authored by Moriasi and al. (2019). The paper related is given below, and the tool itself is freely available on ARS-USDA website, software section.
